Be it known that I, VICTOR SJsrRM, a

the city of Los Angeles, inthe county `of Angeles, in the State of California, liave invented certain new and useful Improvements in Spiral Pumps and Propellers, of which the following is a full,.clear, and exact description and specification, reference being had to the annexed-.sheet of drawings and to the letters marked thereon.

` My invention, which relates to 'certainnew and useful improvements in spiral pumps and propellers, has for its object not only to render vsuch pumps and ropellers more eiiicient than hitherto, but a so to provide'a simple cheap' vconstruction of such devices with a very effective'packing between the rotating and stationary parts packing between the cylindrical citizen of the Kingdom of Sweden, residingin os the rotating screw part `an casingwithin which such part rotates-and by which construction also my im roved spiral pump or propeller is capable o being easily taken to pieces and assembledv whenever re uired. 4

n the annexed drawings, Figure 1 is a ver-y improved spiral pumpor' propeller. Fi 2 is a transverse section thereof on the ine a a, Fig. 1, showing the'anr tii'riction-rollers between the packings. Fi Sis another horizontal section on the line 12%, o enings to the screw throu h which t e water to be pumpe or propellev passes into the screw. In. Figs.'v 1, 2,w 'and 3 the inner cylindrical casing and member of the device is marked A, and 4it contains a double spiral 'B and C, which extends, respectively, from the `bottom of the member D to .the top thereof. This'spiral memberis fitted by a joint E to a vertical rotativeshaft F, and the exterior of the member A forms va continuous cylinder,

consists of the'cylinder `ortube K, having its uplper and lower ends screw-threaded inten-.f7 na y, as shown at Fig. 1, and into these screw-threaded portions the correspondinglyf screw-threaded glands L and M are'frespcctively en tered, sothat 'they compress the exterior of the spiral member the metallic packing-ring 0.

is fixed by screws P,'"as shown at Fig. 1, and

Within the cylindrical portion K the ring Q is" lsecured by screws R, as also shownat Fig. 1.

The ring O therefore rotates with the spiral member A,- while the ring Q remains stationf. ary, the rings O and Q having between them a sspace whereinto ythe antifriction ball-rollers S S S are placed, as shown at Figs. 1 and 2. From this construction it follows .that'as the movable rotated 1t e antifriction-ro lers S S S S not only enable the pump to be operated with. considerable reduction of friction, N N N N above and below are enabled to be a perfectly tight but is to say, rotative.-

The pump-casing is provided with a lubricating-.pipe U for conveying lubricant to the It is to be understood that in place of using parts of the pum or propeller are while the rings i gradualdegree by the the rotatingand fixed p ump or pro eller is disch'ar ed through the lift-pipe T, ich a branch pipe is conf ypacking and rotating parts of the pump, as l shown in Fig. v1.

a single row of antifriction ball-rollers S S S S two or lmore rows of Asuch balls may be used and correspondingly-situatedaccordin` to the lsize and weight of the pump or propeller, also that one, two, ormore spiral passages vmay be used in the propeller.

IOO

said invention and thebest system, mode, or

manner I am at present acquainted with for carrying thesame into eiect, I desire to `ob`l serve 1n conclusion that m said invention may alsobe used as a propel er for ships, and

that what I consider to be novel'and original,

and therefore claim as thein` cured to me by Letters Patent, is as follows:

vention to be se- The combination ofthe tube-inclosed'spi-'- ral passages and driving-shaft, the casing within which the .tube inclosed Spiralpas'# 'sages rotate, they helical directingblades and.;

admission --ports iii the suction pipe, the smiling-boxes and glands in' the pump-casing tube-inclosed spiral passage, said glands and stuffing-boxes togetherwith the pump-easing providing a continuous suction and discharge pipe and casing inolosing the tubelinelosed spiral passages of practically the same diameter throughout their entire lengt-h, the packing, the tfube-inclosed spiral passages, the antifriet-ioir-bearings, the packing-rings, all conslituting the inilproved pump or 1 rsubstantially as i of such enlarged diameter as to receive the i ropeller ereinbe ore descrl ed. In testlmony whereof i have hereunto set my hand and seal, this 10th day of Novem 15 ber, A.' D. 1900, in the presence of two subscribing witnesses.
